2015 BMW M4 MotoGP Safety Car unveiled

The latest version of the BMW M4 Coupé is set to head the Safety Car fleet for the 2015 MotoGP World Championship. BMW has not revealed precise figures, but it says that a new and innovative water-injection cooling system has boosted the six-cylinder engine's power output.

The water-based cooling system is located in the boot, with a five-litre tank, a water pump, sensors and valve delivering water to the injectors at a pressure of 10bar. According to BMW, the water tank will only need to be refilled every fifth tank of petrol, even if the car is being driven at high speed on motorways.

The water-based cooling system supplements the standard cooling system and aims to regulate the temperature of the turbocharger at track speeds, in order to enable the safety car to keep performing at higher speeds for longer.

While this system is not available on any car other than the M4 safety car for now, BMW has said it will be used on an M-series model in the near future, following testing in the MotoGP car, thus hinting to a possible Clubsport version of the M4.

While the fire extinguisher, LED lights and the large 'M' decals on the side of the car are not likely to make it to any production model, it could take several visual cues from the features on the MotoGP car, such as a large carbonfibre rear spoiler, a carbonfibre front and rear splitter, M Performance side skirts and carbonfibre wing mirror caps.
